I'd use this approach, distinguish by whiteboard metadata. It's easier for people to propose (you need to remember just 2 different tracker aliases), and it should not require too many blockerbugs modifications (the Propose page can stay exactly the same, and in the list view which just add some column or tag to distinguish different blocker types).
